Function

Catalyzes the last irreversible step in the biosynthesis of L-serine from carbohydrates, the dephosphorylation of O-phospho-L-serine to L-serine (PubMed:12213811, PubMed:15291819, PubMed:9222972, PubMed:14673469, PubMed:25080166). L-serine can then be used in protein synthesis, to produce other amino acids, in nucleotide metabolism or in glutathione synthesis, or can be racemized to D-serine, a neuromodulator (PubMed:14673469). May also act on O-phospho-D-serine (Probable).

Notes

Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

This product is a recombinant monoclonal antibody, which offers several advantages including:

  • - High batch-to-batch consistency and reproducibility
  • - Improved sensitivity and specificity
  • - Long-term security of supply
  • - Animal-free batch production

For more information, read more on recombinant antibodies.

Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.

This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.

Activity summary

Phosphoserine phosphatase (PSPH) also known as O-phosphoserine phosphohydrolase plays an essential role in serine biosynthesis by catalyzing the conversion of O-phospho-L-serine to L-serine. PSPH is a protein with a molecular weight of approximately 25 kDa. It is expressed across a wide range of tissues with notable expression in the liver kidney and brain. The enzyme activity of PSPH ensures the availability of serine a non-essential amino acid involved in multiple biochemical processes.

Biological function summary

Phosphoserine phosphatase contributes significantly to cellular metabolism and growth by its involvement in the serine biosynthesis pathway. This pathway is important for providing serine which acts as a precursor for proteins nucleotides and other biologically important molecules. PSPH does not function as part of a larger complex; however its enzymatic action is critical for maintaining levels of serine when dietary intake is low. In addition to its role in metabolism PSPH influences cell proliferation and differentiation through providing the necessary serine reserves.

Pathways

Phosphoserine phosphatase integrates into the serine biosynthesis pathway and shows a connection to the glycolytic pathway. The enzyme catalyzes one of the final steps in the phosphorylated serine synthesis process that branches from glycolysis. This pathway features interactions with enzymes like 3-phosphoglycerate dehydrogenase (PHGDH) and phosphoserine aminotransferase 1 (PSAT1) which work sequentially to produce 3-phosphoserine from 3-phosphoglycerate. PSPH follows these enzymes completing the conversion to serine and connects the serine biosynthesis cycle to broader metabolic activities.

Associated diseases and disorders

Altered expression or function of phosphoserine phosphatase associates with conditions such as cancer and neurodegenerative diseases. Within oncogenesis elevated activity of PSPH can supply cancer cells with serine needed for rapid proliferation and this enzyme interplays with other metabolic proteins like PHGDH in cancer metabolism. In neurodegenerative disorders deficient PSPH activity disrupts serine availability leading to harmful effects on the nervous system. Understanding PSPH's role in these conditions can provide insights into therapeutic strategies targeting serine metabolism.

    Western blot - Anti-PSPH antibody [EPR26995-88A] - BSA and Azide free (ab306578)

    This data was developed using Anti-PSPH antibody [EPR26995-88A] ab306577, the same antibody clone in a different buffer formulation.

    Western blot: Anti-PSPH antibody [EPR26995-88A] (Anti-PSPH antibody [EPR26995-88A] ab306577) staining at 1/1000 dilution, shown in green; Mouse anti-Alpha Tubulin [DM1A] (Anti-alpha Tubulin antibody [DM1A] - Loading Control ab7291) loading control staining at 1/20000 dilution, shown in magenta. In Western blot, Anti-PSPH antibody [EPR26995-88A] ab306577 was shown to bind specifically to PSPH. A band was observed at 25 kDa in wild-type A549 cell lysates with no signal observed at this size in PSPH knockout cell line. To generate this image, wild-type and PSPH knockout A549 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.
